The Indo Pro is ideal for big riders (6 feet tall and over) because this model offers a larger deck (42″ x 15″) with the pro roller (8-1/2” diameter) which accommodates a wider stance resulting in greater stability. This model is also great for more advanced strength training movements such as weighted squats and lunges. The larger diameter roller may appear intimidating because the user is higher off the floor than the Original roller. However, it is slower due to the increased weight of the deck and roller. The Indo Pro is also a favorite amongst those users that want to perfect the ability to cross-step and walk from one end of the deck to the other while keeping their weight and center of balance over the roller.
